Given that 8
x
−
7
y
=
11

Find
x
when
y
=
3

x = 4

Step-by-step explanation:

Given that

8 x − 7 y  =  11

Find  x  when  y  =  3

8x - 7(3) = 11

8x - 21 = 11

8x = 32

x = 4

x = 4

Step-by-step explanation:

8x - 7y = 11, y = 3 so replace y in the equation with 3

8x - 7(3) = 11

8x - 21 = 11

add 21 to both sides

8x - 21 + 21 = 11 + 21

8x = 32

divide by 8

8x/8 = 32/8

x = 4
